TO ALL' WHOM IT MAY CONCERN: I

Be it known that I, DARIEL W. CoLBUnN, o'f Laomi, in the county of Sang'iimon, and State of Illinois, have invented a new nnd useful Improvement in Aims and Hatchets; and I do hereby declare that the following is'a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, referencebcing had to the accompanying drawings, forming part of this specification.

I This invention relates to an'improved form of axe, and consists in giving to the edge a semicircular shape. In the accompanying d1'awings-v Figure 1 is a side view of the blade of my improved axe.

Figure2 is an end view thereof.

Similar letters of reference indicate corresponding parts.

A is the flat side of the blade; B the eye to receive the shaft or handle; 0 G C the edge, which, in shape, is a semicircle, or nearly so.

.The effect of this semicircular edge is to convert'each blow of the axe into a drawing cut, andhy its use a \\'00dman can chop from twenty-five to thirty-five per cent. more wood in a day than with the axe now in common use. v

Having thus descrihed my invention, what I claim as new, and desire to secure by Letters Patent, is-

An axe having its edge shaped as a semicircle, substantially as and for the purpose described.

The above specification of my invention signed me this 11th day of March, 1867.
